Editors preference page

Each file that is opened in an editor is stored in a list of
recently used files in the File menu.
This option controls the number of files that is displayed in that list.

4

Show multiple editor tabs

Specifies whether you wish to show multiple editor tabs.
If off, editor workbooks have one large tab and all non-visible editors are accessible only from
the chevron.

On

Close editors automatically

Specifies whether or not to re-use editors in the Workbench.
If on, you may specify the number of editors to use before they are recycled
(the default is 8).
You can also specify if a prompt dialog should be opened or if a new editor should be opened
when all editors are "dirty" (have unsaved changes).
Once it is turned on, the Pin Editor action is added to the toolbar and editor tab menu.
Pinned editors are not recycled.
